DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a moisture-permeable, waterproof fabric of nylon 66 multifilament yarn. More specifically, the present invention relates to a moisture-permeable and waterproof fabric made of a bulky nylon 66 multifilament yarn and having reduced rubbing noise.

[0002]

2. Description of the Related Art Conventionally, sportswear such as blousons and windbreakers have been commercialized with a fabric using spun-like processed yarns made of polyamide-based multifilaments, and have become a wide market in conjunction with the recent jogging boom. However, many people have experienced the rubbing noise of the windbreaker during jogging. As a result of investigating the cause of the rubbing noise, it was found that the rubbing noise was larger as the contact area between the fabrics of the windbreaker at the time of contact and the harder the fabric was. In particular, it was also found that sounds in the high-frequency range of 4 KHz or more were harsh.

[0003] In order to make these sports garments waterproof, a back surface of the cloth is usually coated with a resin, rubber, or the like, but the coating increases the hardness of the cloth and increases the contact area when the cloths come into contact with each other. Cause If the method of reducing the coating thickness is adopted to avoid this, the hardness of the coated fabric is reduced, but the function (permeability and waterproofness) that the coating layer should originally perform is impaired, or the function is repeated each time it is worn and washed In the case where the decrease is extremely extreme, there is a problem that the coating layer is lost.

Conversely, when a cloth made of thin non-bulky yarn is used, the thickness of the coating layer can be reduced because the cloth surface is flat, but the rubbing noise is increased due to the increase in the surface area at the time of contact due to the flatness of the cloth surface. Becomes bigger and becomes paper-like, resulting in poor merchantability. In order to reduce the surface area at the time of contact between the fabrics, it is conceivable to use a bulky yarn. However, since the coating surface is not flat, the thickness of the coating layer cannot be reduced as compared with a fabric made of non-bulky yarn. Of the bulky yarns obtained by drawing ordinary undrawn yarns, thinning the single yarn denier results in a soft bulky yarn, which improves the flatness of the coating surface.Thus, the thickness of the coating layer can be reduced. it can.

[0005] Furthermore, by increasing the weaving density of the cloth, it is possible to prevent the coating liquid from seeping out to the opposite surface. However, nylon 66 obtained by drawing an ordinary undrawn yarn is used.
In the case of a multifilament yarn, the yarn becomes denser and harder with the shrinkage in the dyeing process, and the rubbing noise increases. As described above, a moisture-permeable and waterproof fabric that satisfies a span-like feeling and suppresses a rubbing sound has not yet been disclosed.

[0006]

SUMMARY OF THE INVENTION An object of the present invention is to suppress rubbing noise even when fabrics come into contact with each other, particularly unpleasant noise in a high-frequency region of 4 KHz or more, without impairing the function which the coating layer should originally perform. An object of the present invention is to provide a moisture-permeable, waterproof fabric having a span-like feel.

[0007]

Means for Solving the Problems The present inventors have conducted intensive studies with the aim of obtaining a moisture-permeable and waterproof fabric in which rubbing noise is suppressed even when the fabrics come into contact with each other, and as a result, the present invention has been reached.
That is, in the present invention, in a fabric obtained by laminating or waterproofing a polymer film on a multifilament fabric, the initial modulus of the fiber is 210 to 350 kg / mm ² , and the peak height of the mechanical loss tangent ((tan δ) _max ) And a peak temperature (T _max ) satisfying the following relationship: T _max +320 (tan δ) _max ≦ 132, and a bulky yarn obtained from a nylon 66 multifilament having a single yarn denier in the range of 0.1 to 0.55 denier is woven. A moisture-permeable, waterproof fabric characterized by being used for wefts and warps, or wefts or warps.

[0008] The moisture-permeable and waterproof fabric of the present invention is a moisture-permeable and waterproof fabric in which the contact area is suppressed even when the fabrics are in contact with each other, and harsh sounds in a high-frequency region of 4 KHz or more are suppressed. Initial modulus of fiber is 210-350 kg / mm
The nylon 66 multifilament yarn No. ² is obtained by adjusting the birefringence Δn at the center of the fiber to 45 × 10 ^{−3 to} 52 × 10 ^{−3 according} to spinning conditions such as spinning speed and draw ratio. Here, the birefringence Δn has a value measured by an interference microscope by a method described later.

The peak height ((tan δ) _max ) of the mechanical loss tangent (tan δ) and the peak temperature (T _max ) [° C.]
Satisfies the relationship of T _max +320 (tan δ) _max ≦ 132, because the nylon 66 multifilament yarn is 4
It can be obtained by high-speed spinning at a speed of 000 m / min or more. (JP-A-57-143514, etc.).

The single yarn denier of the nylon 66 multifilament yarn used in the present invention must be in the range of 0.1 to 0.55 denier. Above 0.55 denier, the obtained fabric has a fold index (L / H) of> 0.1.
It becomes larger than 0 and the feeling becomes hard. Further, at a density of 0.1 denier or less, the spinnability of the filament is poor, and the fluff frequently occurs, and industrial production is difficult at present.

A typical example of the nylon 66 multifilament yarn polymer used in the present invention is a practical homopolymer containing 95% by weight or more of polyhexamethylene adipamide polymerized from hexamethylene diamine and adipic acid. Can be obtained by a known polymerization method. The cross-sectional shape of the nylon 66 multifilament yarn used in the present invention is round, Y-shaped, L-shaped, triangular, rectangular, pentagonal, hollow, star-shaped, and has many irregularities on the outer periphery of the yarn cross-section obtained by weight reduction processing. Variations such as possessed ones can be used. Further, it may contain additives usually added to the polyamide filament yarn, such as a matting agent, a stabilizer, and an antistatic agent. The degree of polymerization of the polymer is not particularly limited as long as it is within a range for ordinary fiber formation.

[0012] The method for obtaining a bulky yarn used in the present invention comprises the following steps: the nylon 66 multi-filament yarn obtained by high-speed spinning at a speed of 4000 m / min or more is supplied to a core yarn and a sheath yarn by a difference in feed amount. Any of a method of performing fluid disturbance treatment without attaching, a method of performing fluid disturbance treatment with an overfeed rate of the sheath yarn being larger than that of the core yarn, or a false twisting process may be used.

With respect to the bulky yarn obtained by the fluid disturbance treatment method, if the number of loops having a diameter of 0.6 mm or more out of the loops protruding from the yarn surface is controlled to 200 or less, a fastener phenomenon will occur. is necessary. Also,
30 loops projecting 0.15 mm or more from the yarn surface
0 or less, the number of protruding loops of 0.35 mm or more is 80
Hereinafter, when the number of protruding loops of 0.6 mm or more is 50 or less, it is not preferable because the bulkiness is poor and a paper-like appearance is provided.

The bulky yarn obtained by false twisting has a crimp shape factor (CE / N) of 0.3 to 0.5, which will be described later, in order not to make the appearance paper-like and to cause a fastener phenomenon. Preferably, there is.
A woven fabric using this bulky yarn as a weft and a warp, or a weft or a warp, is a nylon 66 obtained by stretching a normal undrawn yarn.
Since the bulky yarn obtained from the multifilament yarn has a smaller boiling water shrinkage ratio than the woven fabric used for the weft and the warp, the weft or the warp, the fabric does not have a densification in the dyeing process and can have a soft texture. Things.

The moisture-permeable and waterproof fabric of the present invention is a moisture-permeable and waterproof fabric (a) obtained by laminating a microporous film on a woven fabric composed of bulky yarns used in the present invention by a coating method.

When the polymer solution is applied to the fabric to form a microporous film, if the solution easily penetrates into the inside and the back of the fabric, it is not preferable in terms of feeling and quality. It is preferable to perform pretreatment with a water repellent such as a silicone type. The adhesion amount of the water repellent affects the density of the fabric and the viscosity at the time of application of the polymer solution, but is preferably in the range of 0.04 to 0.1% by weight. When the content is 0.04% by weight or less, the polymer solution easily penetrates into the back surface of the woven fabric, and when the content is 0.1% by weight or more, the peel strength between the woven fabric and the microporous film is significantly reduced.

The method of applying the polyurethane polymer is not particularly limited. Generally, a floating knife coater, knife over roll coater, reverse roll coater, roll doctor coater, gravure roll coater, kiss roll coater, nip roll coater and the like are used.
